Texas Instruments AMC0x00D/-Q1 Reinforced Isolated Amplifiers

Texas Instruments AMC0x00D/-Q1 Reinforced Isolated Amplifiers are precision, galvanically isolated amplifiers with a ±250mV differential input and differential output. The input is optimized for direct connection to a shunt resistor or other low-impedance signal source. The isolation barrier separates parts of the system operating at different common-mode voltage levels. The isolation barrier is highly resistant to magnetic interference. This barrier is certified to provide reinforced isolation of up to 5kVRMS (DWV package) and basic isolation up to 3kVRMS (D package) (60s).

The Texas Instruments AMC0x00D/-Q1 outputs a differential signal proportional to the input voltage. The differential output is insensitive to ground shifts and enables routing the output signal over long distances. The AMC0x00D/-Q1 comes in 8-pin wide- and narrow-body SOIC packages and is fully specified over the temperature range from -40°C to +125°C.
